The Majorana Hopping and Constraints in the Anti-de Sitter Spacetime
Chia-Li Hsieh, Vahideh Memari, Mustafa Halilsoy
Comformally flat spacetime converts the Anti-de Sitter (AdS) spacetime into a z-dependent metric. We take advantage of this metric to solve Dirac equations in the AdS geometry anal…

Charged particle geodesics and closed timelike curves in an electromagnetic universe
M. Halilsoy, V. Memari
The spinning electromagnetic universe, known also as the Rotating Bertotti-Robinson(RBR) spacetime is considered as a model to represent our cosmos. The model derives from differen…
